Abstract: After a cow has been milked out and the milking claw has been detached from the cow, the milking vacuum to the claw is shut off and a cleansing solution mixed with air is forced through a portion of the milk line and out through the claw and the teat cup inflations. The cleansing liquid may contain a disinfectant such as iodine to control the transmission of infection from cow to cow carried by the surfaces of the teat cup inflations. A blast of cleansing and drying air is provided following the cleaning cycle to force out any remaining liquid in the milk line, claw and inflations, to thereby eliminate residual disinfectant in these parts. The apparatus is capable of use with automatic detaching equipment, wherein it automatically shuts off the milking vacuum as the milking claw is detached, provides the cleansing liquid and blow out air in timed sequence, and resets to await initiation of another milking cycle.
